hallo everyone,(adsbygoogle = window.adsbygoogle || []).push({});

I have a problem which i cant solve. Does somebody know how to solve this problem?? The question is:

A 220 V electric heater has two heating coils which can be switched such that either coil can be used independently or can be connected in series or parallel, yielding a total of four possible configurations.

The warmest setting corresponds to 2000 W and the coolest corresponds to 300 W.

R1 > R2

Determine the resistance of R1 [in Ω].
